comment number of ways to stack n distinct objects into k distinct boxes
Ok, so from stars and bars, we can place k-1 dividers in $^{n+k-1}C_{n-1}$ ways, and then multiply it by n! ?

comment Why does $\sin(0)$ exist?
I understand sine definition from unit circle, but that "y coordinate" definition itself comes from triangle formed, right ? If not, then how y-coordinate was chosen for definition for sine ?

@GrahamKemp : But doesn't that definition of $\sin(\alpha)$ come from the triangle formed there in the circle?

@DaenerysNaharis But in unit circle also, isn't sine defined in terms of triangle only i.e. because hypotenuse is 1 there, then only we can say that sin(x) is length of perpendicular ?
